I had a sudden attack of hiccups last afternoon. It was annoying, embarrassing and, after a while, a little painful. I searched on the internet for remedies. I tried swallowing air, unsuccessfully. Warn water was a little more helpful, it reduced the intensity but did not cure.
I exercised in the evening and it disappeared after that, but reappeared as soon as I had dinner. After about half an hour my throat was beginning to get a little sore from the hiccuping so I drank a tablespoonful of bees honey. It soothed the throat and cured the hiccups immediately.
